Latest Patents

One of his latest patents is titled "Slotted impingement cooling of airfoil leading edge." This invention pertains to a coolable gas turbine engine airfoil designed for blades or vanes. It features an outer airfoil wall with pressure and suction sides that extend chordwise between the leading and trailing edges. The design includes a leading edge cooling plenum formed between a forwardmost span rib and the outer wall, along with a cooling air channel within the airfoil. A slotted cooling air impingement element is integrated into the span rib, allowing cooling air to be directed onto the interior surface of the outer airfoil wall. This innovative cooling mechanism enhances the performance and durability of gas turbine components.

Another notable patent by Fargher is "Preparation of components having a partial platinum coating thereon." This invention involves the preparation of curved components, such as turbine airfoils, with a platinum or platinum-aluminide protective coating applied to only a portion of the surface. This selective coating can serve as an environmental coating or as a bond coat in a thermal barrier coating system. The method allows for effective protection while optimizing material usage.
